Bei solchen folienartigen Schichtstoffen mit miteinander verklebten Schichten behindert das Klebemittel die Gasdurchlässigkeit; auch ist der Klebemittelverbrauch verhältnismäßig groß. Man hat deshalb auch schon beim Kaschieren von elastischem Schaumstoff mit Textlien od. dgl.

Auch ist bei dickeren, miteinander zu verbindenden Schichten die erzielbare Haltbarkeit der Verbindung beschränktThis procedure is not easy to carry out, especially when intersecting seam zones have to be provided. Also with thicker ones, Layers to be connected to one another limit the achievable durability of the connection

Aufgabe der Erfindung ist es, einen Schichtwerkstoff der eingangs genannten Art zu schaffen, bei dem auch bei Verwendung eines nichtschmelzbaren Deckscbichtmaterials, beispielsweise von Textümateriaä aus nativen Fasern, der gute Verbund der Schichten erhalten bleibt oder möglichst noch verbessert wird, ohne daß eine zusätzliche Haftvermittiungsschicht in dem Schichtwerkstoff vorgesehen werden muß. Außerdem will die Erfindung ein Verfahren schaffen, das es gestattet, diesen Schichtwerkstoff in einfacher, kostensparender, rationeller Weise herzustellen.The object of the invention is to provide a layer material of the type mentioned at the beginning, in which, even when using a non-meltable cover layer material, for example, of textile materials made from native fibers, the good bond between the layers is retained or is improved as far as possible without an additional adhesion promoting layer in the layer material must be provided. In addition, the invention aims to create a method that allows this layer material to produce in a simple, cost-saving, rational way.

Zur Lösung der Aufgabe ist gemäß dem ersten Teil der Erfindung der Schichtwerkstoff dadurch gekennzeichnet, daß bei aus nichtschmelzbarem Material bestehender Deckschicht die Schweißstellen im Bereiche der Deckschicht aus einem lediglich an den Schweißstellen vorhandenen, eigens aufgebrachten schmelzbaren Deckschichtverankerungsmaterial bestehen. To solve the problem, according to the first part of the invention, the layer material is characterized in that that in the case of a cover layer made of non-meltable material, the welds in the area the top layer from a specially applied one only present at the welds fusible face sheet anchoring material exist.

Durch das an den Schweißstellen vorhandene, eigens aufgebrachte schmelzbare Deckschichtverankerungsmaterial wird zusammen mit dem aufgeschmolzenen Material der Innenschicht erreicht, daß die nichtschmelzbare Deckschicht von beiden Seiten aus während des Schweißvorganges mit geschmolzenem Material durchtränkt wird, so daß eir^ einwandfreie hochbelastbare Verbindung an den Schweißstellen zustande kommtDue to the specially applied fusible surface layer anchoring material present at the welding points together with the melted material of the inner layer, the non-meltable outer layer is achieved from both sides is saturated with molten material during the welding process, so that eir ^ perfect Heavy-duty connection is made at the welds

Zur Herstellung des neuen atmungsaktiven Schichtwerkstoffes wird das eingangs beschriebene Verfahren gemäß diesem Teil der Erfindung derart ausgestaltet, daß das Deckschichtverankerungsmaterial in Form einer Folie außen auf die Oberfläche der Deckschicht aufgelegt wird, die Bildung der Schweißstellen unter Durchtränkung der Deckschicht mit dem aufgeschmolzenen Material der Folie erfolgt und die Folie danach unter Ausreißen an den Schweißstellen entfernt wird.The method described at the beginning is used to produce the new breathable layer material designed according to this part of the invention such that the top layer anchoring material in the form a film is placed outside on the surface of the cover layer, underneath the formation of the welds The top layer is impregnated with the melted material of the film and then the film is removed with tearing at the welds.

In den vorliegenden Unterlagen wird mit dem Begriff »nichtschmelzbare Schicht« eine Schicht oder Lage aus einem Werkstoff bezeichnet» der unter Wärmeeinwirkung nicht schmelzbar oder erweichbar ist bzw. als nicht geeignet für eine übliche Schmelzbehandlung durch Erwärmen angesehen wird. Eine solche nichtschmelzbare Schicht kann aus faserigem Gut bestehen, beispielsweise gewebte Textilien, nichtgewebte (non-woven) Textilien, Schnüre oder Litzen, Baumwollstoffe usw.,In this document, the term “non-meltable layer” is used to denote a layer or layer means a material »which is not meltable or softenable under the influence of heat or which is not is considered suitable for ordinary enamel treatment by heating. Such a non-meltable one Layer can consist of fibrous material, for example woven textiles, non-woven (non-woven) Textiles, cords or braids, cotton fabrics, etc.,

ίο oder aber auch aus geschäumten Kunststoff-Schichten und ähnlichem. Als Beispiele für das faserige Gut seien Naturfasern, glasfaserverstärkte Kunststoffasern und eine Mischung dieser beiden Faserarten genannt Als »schmelzbare Schicht« wird jede Schicht aus irgendeinem Werkstoff, der zum Schmelzen oder Erweichen durch eine übliche Wärmebehandlung geeignet ist bezeichnet Eine solche Schicht kann aus faserigem Gut, beispielsweise gewebte Fasern, nichtgewebte Fasern. Schnüre oder Litzen, Stoffe u.a. oder auch aus geschäumten Kunststoffen, bestehen. Als Beispiele seien thermoplastische Kunststoffasern wie etwa Nylon, Polyacryl, Polyester und Polypropylen genannt; außerdem Kunststoffasern mit einer gewissen Naturfaser-Beimischung sowie geschäumte thermoplastische Kunststoffe, wie Polyurethan-, Vinylchlorid-Schaum usw.ίο or also made of foamed plastic layers and the like. Examples of the fibrous material are natural fibers, glass fiber reinforced plastic fibers and a mixture of these two types of fibers called a "fusible layer" each layer is made up of something Material that is suitable for melting or softening by a conventional heat treatment Such a layer can be made of fibrous material, for example woven fibers, non-woven fibers. Cords or strands, fabrics, etc. or also made of foamed plastics. As examples are thermoplastic synthetic fibers such as nylon, polyacrylic, polyester and polypropylene called; aside from that Synthetic fibers with a certain admixture of natural fibers as well as foamed thermoplastics Plastics such as polyurethane, vinyl chloride foam, etc.

Die nichtschmelzbaren und die schmelzbaren Schichten können in vielen Kombinationen zu Schichtwerkstoffen verbunden werden, wobei zumindest eine nichtschmelzbare Schicht als Deckschicht eine der äußeren Oberflächen des Schichtwerkstoffs bildet. Wird eine nichtschmelzbare Schicht mit A und eine schmelzbare Schicht mit B bezeichnet so ergibt sich folgende Darstellung einiger Beispiele aus der Vielzahl möglicher Kombinationen: A-B, A-B-A, A-BX-B2, A-B-A-B, A-Bi-B2-A, A-B\-B2-B\ A-B-A-B-A usw. Mit BX, B 2, B3 werden unterschiedlich aufgebaute Schichten bezeichnet, wie beispielsweise ein kattunartiges Gewebe, eine geschäumte Schicht, ein Textilstoff usw.The non-meltable and the meltable layers can be connected in many combinations to form layered materials, with at least one non-meltable layer as a cover layer forming one of the outer surfaces of the layered material. If a non- meltable layer is designated with A and a meltable layer with B , the following illustration of some examples from the multitude of possible combinations results: AB, ABA, A-BX-B2, ABAB, A-Bi-B2-A, AB \ -B2 -B \ ABABA etc. BX, B 2, B3 denote differently structured layers, such as a calico-like fabric, a foamed layer, a textile material, etc.

Ein Beispiel eines erfindungsgemäßen Verfahrens zum Hersteilen eines atmungsaktiven Schichtwerkstoffs wird nachfolgend erläutert.
Auf beide Oberflächen einer zusammengesetzten Schicht A-B-A wird je eine schmelzbare Folie C eines Deckschichtverankerungsmaterials aufgebracht. Danach wird die sich ergebende Schichtkombination C-A -B-A -C stellenweise zusammengedrückt wobei die Druckstellen punkt- oder linienweise ausgebildet sein können. Man läßt den Druck eine zeitlang einwirken, so daß die schmelzbare Folie C und die schmelzbare Schicht B aufgeweicht werden und von beiden Seiten her in die nicht schmelzbare Schicht A eindringen und diese durchtränken. Dabei werden die schmelzbare Folie und die schmelzbare Schicht auf das engste mit der nichtschmelzbaren Schicht A verklebt oder verbunden und bilden dadurch einen Schichtwerkstoff. Zum Aufschmelzen der schmelzbaren Folie und der schmelzbaren Schicht werden bekannte Mittel, beispielsweise Ultraschallwellen, Hochfrequenzheizung, Widerstandsheizung usw. je nach Bedarf verwendet. Nachdem das Verbinden oder Verkleben beendigt ist, wird die schmelzbare Folie C von der zugeordneten nichtschmelzbaren Schicht abgenommen oder abgezogen. An example of a method according to the invention for producing a breathable layer material is explained below.
A fusible film C of a cover layer anchoring material is applied to both surfaces of a composite layer ABA. Then the resulting layer combination CA -BA -C is pressed together in places, whereby the pressure points can be formed in points or lines. The pressure is allowed to act for a while, so that the fusible film C and the fusible layer B are softened and penetrate into the non-fusible layer A from both sides and soak it. The fusible film and the fusible layer are glued or connected as closely as possible to the non-fusible layer A and thereby form a layer material. Known means, for example ultrasonic waves, high-frequency heating, resistance heating, etc., are used as required for melting the fusible film and the fusible layer. After the joining or gluing is completed, the fusible film C is peeled off or peeled off from the associated non-fusible layer.

Da aber die aufgeschmolzenen Stellen der Folie eng und dauerhaft mit der nichtschmelzbaren Schicht verbunden sind, werden beim Abziehen der Folie diese (punkt- oder strichweisen) Stellen aus der Folie ausgerissen. Die FolieBut because the melted areas of the film are closely and permanently connected to the non-meltable layer are, when the film is peeled off, these points (point by point or line by line) are torn out of the film. The foil

kann jeweils mehrfach benutzt werden, indem sie bei jedem Herstellungsvorgang ein bißchen seitlich weitergeschoben wird, so daß jeweils die nicht ausgerissenen Teile auf die zu verbindenden Stellen zu liegen kommen. Als Material für die schmelzbare Folie können unterschiedliche thermoplastische Kunststoffe oder Kunstharze verwendet werden, es empfiehlt sich aber, solche Werkstoffe zu verwenden, die mit den jeweils verwendeten nicht schmelzbaren Schichten verträglich sind. ίοcan be used several times by sliding them a little to the side during each production process so that the parts that have not been torn out come to rest on the areas to be connected. Different thermoplastics or thermoplastics can be used as the material for the fusible film Synthetic resins are used, but it is advisable to use materials that are compatible with the respective non-meltable layers used are compatible. ίο

Eine Vorrichtung zum Herstellen eines Matratzenschoners wird nun anhand der Zeichnung erläutert.A device for producing a mattress protector will now be explained with reference to the drawing.

Aus F i g. 1 ist ein Schichtwerkstoff 1 ersichtlich, der aus einer schmelzbaren Schicht 2 aus einem Polypropylen-Kattun und aus einer nichtschmelzbaren Schicht 3 Is aus Zellulose-Gewebe besteht. Dieser Schichtwerkstoff 1 wird einer Ultraschalleinrichtung zugeführt in welcher das Verbinden oder Verkleben der einzelnen Schichten erfolgt. Die in F i g. 2 schematisch dargestellte Ultraschalleinrichtung besteht aus einem Elektrodenarm 4, einer dem Elektrodenarm 4 gegenüberliegenden Gegendruckwalze 5 sowie einer in Transportrichtung vor der Gegendruckwalze 5 angeordneten Zuführwalze 7 und einer hinter der Gegendruckwalze 5 angeordneten Abzugswalze 6. Die Gegendruckwalze 5 weist 2j mehrere radial aus ihrer Oberfläche herausragende Vorsprünge 8 auf, die mit dem Elektrodenarm 4 zusammenwirken. Der Elektrodenarm 4 wird während der Drehung der Gegendruckwalze 5 bis in die Nähe der Vorsprünge 8 herangefahren. Die Vorsprünge 8 sind in J0 geeigneter Weise über die Mantelfläche der Gegendruckwalze 5 verteilt angeordnet beispielsweise in schraubenförmigen oder parallelen Linien. Während des Zuführens des Schichtwerkstoffs 1 zu der Ultraschalleinrichtung wird Deckschichtverankerungsmaterial in Form einer schmelzbaren Folie 9, beispielsweise aus Polypropylen, im wesentlichen an der nichtschmelzbaren Schicht 3 anliegend, ebenfalls zugeführt, und zwar von der Zuführwalze 7 über die Ultraschalleinrichtung zu der Abzugswalze 6. Der Schichtwerkstoff 1 und die schmelzbare Folie 9 werden dabei zwischen dem Elektrodenarm 4 und dem Vorsprung 8 der Gegendruckwalze 5 zusammengedrückt und gleichzeitig der Einwirkung von Ultraschallwellen ausgesetzt Dabei werden die schmelzbare Schicht 2 und die schmelzbare Folie 9 aufgeschmolzen oder erweicht und durchtränken von beiden Oberflächen her die n'^htschmelzbare Schicht 3. An den jeweiligen Verbindungsstellen werden hierbei auch die Fasern der nichtschmelzbaren Schicht flachgedrückt (vgl. Fig.4), während die Zwischenräume zwischen den einzelnen Fasern durch die Ultraschallschwingungen geöffnet werden, wodurch die schmelzbare Folie und die schmelzbare Schicht 2 miteinander verschmolzen werden können (vgl. F i g. 3). Bei der weiteren Drehung der Gegendruckwalze 5 wird die Folie 9 von dem Schichtwerkstoff 1 abgezogen, wobei aber die den aufgeschmolzenen Befestigungsstellen 10 entsprechenden Bereiche der Folie 9 von dieser ausgerissen werden. Gleichzeitig werden die aufgeschmolzenen Stellen 10 in dem Schichtwerkstoff 1 abgekühlt und verfestigt. Obwohl die danach auf die Abzugswalze 6 aufgewickelte Folie 9 stellenweise ausgerissen ist, kann sie mehrere Male verwendet v/erden, indem sie wie bereits erwähnt bei jedem Aufbringen auf einen neuen Schichtwerkstoff geringfügig in ihrer Lage verschoben wird.From Fig. 1 is a layer of material 1 can be seen, consisting of a fusible layer 2 made of a polypropylene calico and from an infusible layer 3 is from cellulosic fabric. This layer material 1 is fed to an ultrasonic device in which the individual layers are connected or glued. The in F i g. Ultrasonic means, shown schematically 2 consists of an electrode arm 4, a the electrode arm 4 opposed counter-pressure roller 5 and a arranged in transport direction before the platen roller 5 feed roller 7 and, arranged behind the platen roller 5 off roll 6. The platen roller 5 has 2 j plurality of radially protruding from its surface Projections 8 which cooperate with the electrode arm 4. The electrode arm 4 is moved up to the vicinity of the projections 8 during the rotation of the counter-pressure roller 5. The projections 8 are arranged in a suitable manner distributed over the jacket surface of the counterpressure roller 5, for example in helical or parallel lines. While the layer material 1 is being fed to the ultrasonic device, top layer anchoring material in the form of a fusible film 9, for example made of polypropylene, essentially lying against the non-fusible layer 3, is also fed, namely from the feed roller 7 via the ultrasonic device to the take-off roller 6. The laminate material 1 and the fusible film 9 are compressed between the electrode arm 4 and the projection 8 of the counter-pressure roller 5 and simultaneously exposed to the action of ultrasonic waves. The fusible layer 2 and the fusible film 9 are melted or softened and soak the n 'from both surfaces. ^ heat-meltable layer 3. At the respective connection points, the fibers of the non-meltable layer are also pressed flat (see FIG. 4), while the spaces between the individual fibers are opened by the ultrasonic vibrations, whereby the meltable film e and the fusible layer 2 can be fused together (cf. F i g. 3). During the further rotation of the counter-pressure roller 5, the film 9 is pulled off the layer material 1, but the regions of the film 9 corresponding to the melted fastening points 10 are torn from the latter. At the same time, the melted points 10 in the layer material 1 are cooled and solidified. Although the film 9 subsequently wound onto the take-off roller 6 has been torn out in places, it can be used several times by, as already mentioned, being shifted slightly in its position each time it is applied to a new layer material.

Die Schicht 2 aus Kunststoffaser-Kattun und die schmelzbare Folie 9 sind im Bereich der aufgeschmolzenen Stellen sehr eng mit der nichtschmelzbaren Schicht 3 verbunden und die entsprechenden Stellen 10 der nichtschmelzbaren Schicht 3 sind dabei beidseitig von den aufgeschmolzenen Stellen der Kunststoffaser-Kattunschicht 2 bzw. der schmelzbaren Folie 9 bedeckt, wie aus F i g. 4 ersichtlich.The layer 2 made of synthetic fiber calico and the meltable film 9 are in the area of the melted Places very closely connected to the non-meltable layer 3 and the corresponding places 10 of the The non-meltable layer 3 is on both sides of the melted points of the synthetic fiber-calico layer 2 or the fusible film 9, as shown in FIG. 4 can be seen.

Als Folge hiervon ist die schmelzbare Schicht 2 nur unter Schwierigkeiten von der nichtschmelzbaren Schicht 3 wieder zu trennen. Der Schichtwerkstoff weist eine klare Zeichnung in Form der verbundenen oder verklebten Stellen 10 auf, die ein ansprechend wirkendes Steppmuster ergeben. Durch Verwendung einer farbigen Kunststoffolie kann dem Schichtwerkstoff ein ästhetisch wirkendes Aussehen verliehen werden. In Fig.5 ist ein Beispiel eines mit einem Punktmuster versehenen erfindungsgemäßen Schichtwerkstoffs dargestellt Das Muster ist nach Belieben wählbar.As a result, the fusible layer 2 differs from the non-fusible one with difficulty Separate layer 3 again. The layered material has a clear drawing in the form of the connected or glued spots 10, which result in an appealing quilting pattern. By using a colored plastic film can give the laminate material an aesthetically pleasing appearance will. FIG. 5 shows an example of a layered material according to the invention provided with a point pattern shown The pattern is freely selectable.

Da bei einem Schichtwerkstoff gemäß der Erfindung die nichtschmelzbare Schicht 3 mit zwei jeweils beidseitig anliegenden schmelzbaren Schichten eng verbunden ist zeichnet sich der Schichtwerkstoff durch eine starke Haftung zwischen den einzelnen Schichten aus. Außerdem sind die nichtgasdurchlässigen oder nichtflüssigkeitsdichten Bereiche des Schichtwerkstoffs allein auf die verbundenen Stellen 10 beschränkt wodurch eine ausgezeichnete Atmungsfähigkeit oder Durchlässigkeit erreicht wird. Ein weiterer Vorteil des erfindungsgemäßen Schichtwerkstoffes ist sein ästhetisch ansprechendes Aussehen.Since in a layer material according to the invention, the non-meltable layer 3 with two each The layer material is characterized by its fusible layers lying on both sides strong adhesion between the individual layers. In addition, they are not gas-permeable or Non-liquid-tight areas of the layer material limited solely to the connected points 10 whereby excellent breathability or permeability is achieved. Another benefit of the The layer material according to the invention is its aesthetically pleasing appearance.
